Recycling success for new Lokotrack ST3.5

Latest Metso twin-deck mobile screening unit proves effective in Italian recycling operation

THE new Lokotrack ST3.5 mobile screen from Metso has proven its efficiency in a demanding recycling project in Pollenza, south of Rimini, in Italy, where it has been classifying difficult, rock-based recycled materials at around 1,000 tonnes per day to produce consistently clean end products.

‘We plan to use our Lokotrack ST3.5 both in recycling and quarrying,’ said Andrea Renzi, managing director of family-owned quarrying and recycling company ‘Our first impression of ST3.5 is very positive, thanks to its quality components, sturdy design and ease of use.’

In quarrying applications the ST3.5’s optional vibrating grid results in quicker feeding and reduces the need to tilt the grid for cleaning, while in recycling the main benefit is in securing the cleanliness of the end products.

‘The vibrating grid effectively separates wood, plastic and other scrap from the feed, giving us much cleaner screened end products,’ commented Massimo Renzi, who is responsible for recycling. ‘By choosing different grid mesh sizes, we can also easily adjust and control the feed size to the screen.’

Fitted with a 30mm mesh size on the upper deck and a 5mm mesh on the lower deck, and fed by a small shredder unit, the ST3.5’s output in the recycling operation is around 130 tonnes/h.

The Lokotrack ST3.5 used by also features separate remote radio controls for the mobile screen and the vibrating grid, allowing full steering of the unit and easy adjustment of the screening process from the cab of an excavator or wheel loader.
